DC voltage rating of a capacitor

What is the DC voltage rating of this capacitor?


Hello. Welcome to the Technical Forum. Welll the KY per the data shet only lists the : X1 : 250Vac (r.m.s.), Y2 : 300Vac (r.m.s.)

Unfortunately the data sheet is only listing Ac voltage:

It depends on what one means by “DC voltage rating.”

The part is a safety capacitor, and therefore must meet the requirements of the relevant standards, such as IEC60384-14. This standard describes different “ratings” depending on whether one is speaking of the nominal voltage with which a capacitor may be used under the standard, or the maximum voltage that it must be able to withstand.
